分析结果与地质采样结果及海图均吻合,说明本文提出的方法应用于窄带脉冲信号的海底底质分类是适用的。
The result is accord with geological sample and sediment chart, so this method can be applied on sediment classification of narrow-band pulse echo sound signal.
因此,窄带脉冲光束可以采用复振幅包络和复解析信号两种表示式来研究,而对于宽带脉冲光束,必须采用严格的复解析信号表示式。
It is concluded that both of the representations are applicable to study narrowband pulse, but for broadband pulse only rigorous complex analytical signal representation should be adopted.
